Le verdict Dubspot

A free acid bassline synth that behaves like a TB-303 pushed well past the edge. A wavetable voice and resonant filter sit under a deep step sequencer that can automate and randomise nearly everything, and AUv3 means it drops straight into a mobile or desktop DAW. The one-time unlock for full patterns, FX and Song mode is the only cost.

Idéal pour Producers who want a fast, free acid bassline machine on iPhone, iPad or Mac, and anyone chasing generative 303-style lines without hardware.

Pros

Free to download and genuinely usable before the unlock
Wavetable voice with resonant filter for classic acid squelch
Deep step sequencer automates every parameter, with generative behaviour
AUv3 support slots it into iOS and macOS DAWs
Runs on iPhone, iPad and Mac from one app

Cons

Full FX, all 48 patterns, Song mode and preset saving sit behind an in-app purchase
Monophonic acid specialist, not a general-purpose synth
No Windows or VST build, so desktop use is Mac only

Field notes

Aperçu

Fingerlab BloopMachine is a free acid bassline synth-sequencer for iOS and macOS, released on 29 October 2026. Fingerlab, the studio behind DM1 and Mynth, describes it as a TB-303 pushed well past the edge, and the design backs that up: a compact synth voice wired to a sequencer built for movement, squelch and happy accidents.

The sound engine pairs a wavetable oscillator with a resonant filter, the combination that gives acid its rubbery, screaming character. Driving it is a deep step sequencer that can automate every parameter and lean generative, so a single pattern keeps evolving rather than looping flat. The full version carries 48 patterns, a Song mode for arranging them, the complete FX section and preset management.

Because it supports AUv3, BloopMachine loads straight into mobile and desktop hosts like GarageBand, Logic Pro, AUM and Cubasis, or runs on its own. It is free to download and usable before paying, with one in-app purchase unlocking the full feature set. For desktop 303 work it sits alongside Arturia Acid V and TAL-BassLine-101.

Quick reference

FAQ

Is BloopMachine really free?

Yes. BloopMachine is a free download for iOS and macOS and is usable as is. A single in-app purchase unlocks the full version, which adds the complete FX section, all 48 patterns, Song mode and preset saving.

Does BloopMachine work as a plugin?

Yes. It supports AUv3, so it loads inside AUv3 hosts such as GarageBand, Logic Pro, AUM and Cubasis on iOS and macOS, as well as running standalone.

What platforms does BloopMachine run on?

It runs on iPhone, iPad and Mac from a single app. There is no Windows or VST version.

BloopMachine or a desktop 303 like Phoscyon 2?

BloopMachine is free, mobile-first and leans generative. D16 Phoscyon 2 is a paid desktop plugin with deeper 303 modelling and a larger preset library, so it suits a committed studio workflow.
